	VTEC - Wikipedia, the free encyclopedia
		VTEC (standing for Variable valve Timing and lift Electronic Control) is a system developed by Honda to improve the combustion efficiency of its internal combustion engines throughout the RPM range.
		VTEC is the result of an effort to marry high RPM performance with low RPM stability.
		Drivability is a concern for some who are wary of the fact that the VTEC may activate in the middle of an aggressive corner, potentially upsetting the stability and throttle response of the bike.

	VTEC
		The VTEC system used in most Civics (EX, Si and the del Sol Si but NOT del Sol VTEC) is a little closer to that in the NSX, etc. The difference being that this system is vastly simplified and operates on the intake valves ONLY.
		The VTEC is equipped with multiple cam lobes per cylinder, providing one valve timing and valve lift profile at low speed and a different profile at high speed.
		VTEC factoid-of-the-week: Valve timing change conditions that must be met include 5 km/h (3 mph) or faster and 60 degrees C (140 deg F) or faster.

	Hyper-VTEC or Economy VTEC - Sportbike Review - Sport Rider
		In general, VTEC enhances an engine's performance, fuel economy and emissions by controlling the valves differently at low and high rpm.
		An enhancement of VTEC used on the Civic HX and the hybrid Insight (dubbed VTEC-E for efficiency, economy and ecology) is closer to the Interceptor's arrangement, but still utilizes rockers.
		The trouble with grafting these automotive-style VTECs on a bike like the VFR is that bikes have long since outgrown rockers, and the size penalty for extra lobes would be too great given Honda's goals for the 2002 Interceptor.

	All About VTEC - Team Integra
		VTEC, as most of us know, was a way to attack the compromise of low end power vs. high end power.
		There was skepticism about all the small parts involved in the VTEC engine and most manufacturers believed Honda's new engines were going to be full of problems down the road with errors occurring during the VTEC engagement process.
		However it turned out to be quite the opposite as DOHC VTEC engines have proved to be some of the most reliable engines ever built because of their precision.

	Howstuffworks "What does the VTEC system in a Honda engine do?"
		If you have read How Car Engines Work, you know about the valves that let air into the engine and let exhaust out of the engine.
		If you put in a good low-speed camshaft, it hurts the engine's performance at high speeds, and if you put in a good high-speed camshaft it hurts the engine's performance at low speeds (and in extreme cases can make it very hard to start the engine!).
		VTEC (which stands for Variable Valve Timing and Lift Electronic Control) is an electronic and mechanical system in some Honda engines that allows the engine to effectively have multiple camshafts.

		Whether it is the 1.6-liter SOHC VTEC engine found in the 1992-2000 Civic or the 3.2-liter quad-cam Acura NSX engine, manufacturers have found ways in extracting more horsepower from the already potent powerplants.
		One of the common downfalls of VTEC performance camshafts is the dip in the powerband due to early engagement of the VTEC effect.
		From viewing the dyno curve we were able to establish the VTEC was engaging too early, causing a dip in the dyno curve.

		To add a VTEC cylinder head to an LS bottom end, you must tap and plug the VTEC oil supply hole found on the bottom left side of the head.
		The procedure to swap a VTEC head on the B20B is the same as the LS swap with the exception of using the B20 head gasket.
		Checking Clearances - As a warning, when the VTEC head is installed, there is not a whole lot of piston-to-valve clearance as VTEC heads have larger 33mm intake valves vs. the B20 motor's 31mm valves.

	Ls/vtec
		The Ls block does not have a Vtec oil passage (you need this hole to produce the oil pressure to lock the vtec lobes rocker arm) so you will need to tap the hole on the head or weld it shut.
		The oil pumps on the ls's suck so you might want to upgrade to a vtec one or a b20 as they are same part number as the gsr.
		Any 1.6 b-series piston will be raised by about one full point in the ls block like the b16a(pr3 pistons will raise it from the stock 10.2 comp in the b16a to 11.2ish in the ls block so keep this in mind when building the ls block.
